The invention provides a cylindrical sine ripple ring rib pressure-resistant shell. A sine ripple ring rib structure is arranged on the inner surface of the cylindrical sine ripple ring rib pressure-resistant shell in the axial direction, the sine ripple ring rib structure conforms to the ripple morphology of a sine function y = a * sin (2pi x/T), a represents the amplitude of the sine function, and T represents the period of the sine function. According to the technical scheme, the problems that residual stress is generated in ring rib welding and the welding process is tedious in the prior art are solved.

    本发明提供一种圆柱形正弦波纹环肋耐压壳。所述圆柱形正弦波纹环肋耐压壳的内表面沿轴向设置有正弦波纹环肋结构,所述正弦波纹环肋结构符合正弦函数y=a·sin(2πx/T)的波纹形貌,a表示所述正弦函数幅值,T表示所述正弦函数的周期。本发明的技术方案解决了现有技术中的环肋焊接产生残余应力以及焊接工艺繁琐的问题。
